摘要： A method of partitioning an integrated circuit design for physical design verification includes steps of receiving as input a representation of an integrated circuit design having a number of physical design layers and a composite run deck specifying rule checks to be performed on the integrated circuit design. The composite run deck is partitioned into partitioned run decks so that the number of physical design layers referenced by each of the partitioned run decks is a minimum. The representation of the integrated circuit design is parsed to filter only the physical design layers required for each of the partitioned run decks into a filtered data deck for each of the partitioned run decks. The filtered data deck is generated as output for each of the partitioned run decks.

摘要： A tool and method for implementing engineering change orders. The tool and method provides that a change file is checked, equivalent engineering change orders are computed and applied to an active cell. The engineering change orders are registered with a pre-determined tool name, and it is detected and reported if another tool needs to be run to restore routing information. The active cell is not automatically saved after the engineering change orders are applied. Instead, a user must manually save the active cell after the tool is run. The tool can work with three different name spaces: Verilog, VHDL and Avant! Verilog.

摘要： A method of debugging an IKOS model. The method includes mapping information contained in either a .pin or .lde file or both into corresponding files which are more user-friendly, readable and editable. Preferably, a .v file which is readable to create a schematic view of the cell is also created and the schematic view can be viewed and analyzed. Then, the one or more user-friendly files which have been created can be read and edited, and the .pin and/or the .lde file is re-created. Then, a tool is used to analyze the .pin and .lde files again and determine whether there is a functional or timing failure.

摘要： A method and system for performing dummy metal insertion in design data for an integrated circuit is disclosed, wherein the design data includes dummy metal objects inserted by a dummy fill tool. After a portion of the design data is changed, a check is performed to determine whether any dummy metal objects intersect with any other objects in the design data. If so, the intersecting dummy metal objects are deleted from the design data, thereby avoiding having to rerun the dummy fill tool.
